Buying a Car in Washington: Tax, Fees and Insurance
Sales tax. State rate of 6.5% plus a 0.3% motor vehicle tax; local rates add 1% to 3.5%. The calculator uses the state rate of 6.80%; enter your combined local rate for an exact figure. Dealers add the tax to the amount financed unless you pay it at signing, so it costs interest for the life of the loan.
Trade in. In Washington the trade in value is subtracted before tax is figured, so a $10,000 trade in saves $680 in tax on top of lowering the loan.
Fees. Title, registration and plate fees are set by the Washington motor vehicle agency and vary by vehicle; dealer documentation fees are set by the dealer and run from about $100 to more than $800 depending on the state. The calculator uses $300 as a placeholder; replace it with the figures on your buyer's order.
Insurance. The average Washington car insurance premium is about $1,125 a year, or $94 a month, according to the NAIC, compared with about $1,258 nationally. Lenders require full coverage on a financed car, so budget for it alongside the payment. Compare carriers on the Washington car insurance page.
